Moreover, the invention relates to a machine of the tobacco processing industry.
  • a tipping paper leaflet is provided, which on the one hand surrounds the filter and on the other hand connects a head end of the tobacco rod with the filter with a protruding edge.
  • the joining of the filter with the tobacco rod is usually done by gluing.
  • EP-A-1 147 716 There is described a device for applying glue to a wrapping paper or a wrapping paper strip of a rod-shaped article of the tobacco-processing industry. To create a size image with non-adhesive areas on a wrapping strip, the device has means for interrupting the application of glue to the wrapping paper strip.
  • the size of the gluing layer may be too thinly applied to the tipping paper strip, or there may be gaps or interruptions due to process-related disturbances, e.g. Make soiling in the gluing system, so that a sufficient connection between the filter and the tobacco rod is not guaranteed.
  • EP-B-0 418 342 a device for detecting sufficient moisture of the gluing of a paper strip is described, wherein the presence of a gluing on the paper strip to be bonded is detected by means of a capacitive sensor.
  • the present invention seeks to provide a further possibility for determining the amount of glue or mass and for monitoring a gluing on a wrapping strip of the tobacco-processing industry, in particular in the edge regions of the wrapping strip available.
  • This object is achieved by a device for determining and / or monitoring a quantity of glue applied to a wrapping strip of the tobacco processing industry or
  • an ultrasonic measuring system with at least two ultrasonic generating sources for applying the wrapping strip with ultrasound and at least two ultrasonic sensor receiving units for receiving the envelope strip penetrating ultrasonic signals is provided, which is further developed in that in each case between the at least two ultrasonic generating sources and / or between the at least two ultrasonic sensor receiving units, a partition wall is arranged.
  • the invention is based on the idea that in an ultrasonic measuring system by the attachment of partitions or partitions between two ultrasonic sources and / or two ultrasonic receivers, a diffraction of the emitted rays or other artifacts on the ultrasonic measuring system, in particular in the edge region of the paper web or to be tested testing wrapping strip, be avoided.
  • a sound source to a receiver signals from adjacent ultrasonic transmitters are suppressed or shielded by the partitions, so that clear signals can be received and evaluated by a controller or evaluation, whereby a total of a particularly reliable measurement of the amount of glue or a monitoring of the glue pattern is also possible in the edge region of the wrapping strip.
  • the ultrasound is channeled or aligned between an ultrasound transmitter and the respective ultrasound receiver.
  • the measurement principle is based on the fact that a part of the emitted ultrasonic waves is absorbed by the glued paper strip and the unabsorbed part is available as a measuring signal at the receiving sensor, so that the amount of glue of the applied glue is virtually continuously tested and monitored.
  • a paper strip which has been conveyed at high transport speed and glued can be examined for defects in the gluing.
  • the measuring method is a direct measuring method and independent of the composition, eg the water content of the glue.
  • vertical paper fluctuations have little effect on the received ultrasonic measurement signals.
  • the ultrasound is generated by at least two transmitting units, for example in the form of piezoelectric elements, and received by at least two receiving units, for example in the form of piezosensitive microphones.
  • the wrapping strip is ultrasonically applied transversely to the transporting direction, the wrapping strip being passed between the sending unit and the sensor receiving unit. This allows the ultrasound to be oriented with a preferred orientation on the wrapping strip and to penetrate the wrapping strip.
  • ultrasonic transmitting piezoelectric elements are arranged on the glued or non-glued side of the wrapping strip. On the other side, the ultrasonic waves or signals are received by piezo-sensitive microphones or sensors.
  • the wrapping strip is in this case monitored over its entire width, whereby all widths of the wrapping strip can be recorded unformatted with the same measuring system, consisting of a transmitting unit and a sensor receiving unit.
  • the glue content of glue tracks of a glue image preferably in the time average, are detected and / or defective areas of the glue image are detected.
  • At least one ultrasound-generating source and / or an ultrasound receiving unit is arranged between two partitions.
  • the height of the partition wall or the heights of the partition walls are greater than the heights of the ultrasonic generating sources and / or the ultrasonic receiving units.
  • the ultrasonic waves are accurately aligned at the transmitter to the associated receiver, so that the receiver no disturbing ultrasonic signals are received from neighboring transmitters. If the partitions are arranged at the receiver, the measurement disturbing ultrasonic signals from the adjacent transmitters are suppressed or largely avoided.
  • the device can be easily cleaned if at least one partition wall or several partitions is detachably arranged as a structural unit, so that the partition walls are removed or removed for cleaning purposes of the ultrasonic measuring system and then fixed in position again.
  • the cleaning device is designed as an ultrasonic transmitter and / or as a compressed air device. This is a simple way of effective cleaning of the ultrasonic measuring system or reaches the individual components of the measuring system, the design complexity can be kept low.
  • the wrapper strip is routed between the ultrasound generating sources and the ultrasound receiver units, which are spaced apart from each other.
  • the ultrasonic measuring system measuring system can be U-shaped or fork-like.
  • the device is characterized in that piezoelectric elements are provided as ultrasound-generating sources and / or piezosensitive microphones as ultrasound sensor receiving unit. At least two ultrasound sources, in particular piezoelectric elements, and at least two ultrasound sensor receiving units, in particular piezosensitive microphones, are arranged on one limb of the U-shape, and on the other limb of the U-shape. Preference is given to a larger number of ultrasound-emitting piezo elements which are arranged in an array in order to obtain a homogeneous sound field over the entire width of the enveloping strip. An array is also advantageous on the sensor reception side, so that better spatial resolutions can be achieved.
  • the device is further distinguished by the fact that the entire width of the wrapping strip can be monitored by means of the ultrasonic measuring system.
  • the object is achieved by a machine of the tobacco processing industry, which is equipped with a device according to the invention described above for detecting and / or monitoring a coated on a wrapping strip of the tobacco processing industry glue quantity or mass.

  • the glue pattern has a plurality of glue-free areas 17, which are perforated after cutting the tipping paper strip 15 in covering sheets and after wrapping the cut tipping sheets around filter plugs and tobacco sticks by means of processing organs.
  • edge zones are largely responsible for the bonding of the tipping paper to the tobacco rod of the cigarette. Lack of glue at these points leads to loose or falling filters and therefore the application of the glue is particularly important. Therefore, in places more glue is applied in the edge zone area than in the middle zones of the glue pattern.
  • Gluing errors in the center zones can lead to gluing problems in the seam area of the filters, which can be indirectly detected by a downstream pneumatic test system on a test drum, so that the cigarette provided with a faulty glued covering paper leaflet is ejected.

  • the ultrasonic measuring system 10 is connected to an evaluation device 20.
  • the transmission bar 13 and the arrangement of the microphones 14 are designed so that they cover the glue pattern or the amount of glue over the entire width of the tipping paper strip 15. In particular, they are designed to be wider than the maximum format width of a wrapping strip 15. As a result, numerous widths of a tipping paper strip 15 can be recorded without format with the same measuring system 10.
  • a second ultrasonic measuring system which is likewise constructed in the manner of the ultrasonic measuring system 10 shown in the drawing, is arranged in front of a glue application member.
  • This second ultrasonic measuring system measures the fluctuations and influences of the thickness of a not yet glued tipping paper strip 15.

  • the ultrasound measured at the microphones 14 thus always comes from the opposite, associated piezoelectric element 131.
  • the partition walls 21 are arranged relative to one another, whereby a comb-like structure of the partition walls 21 is formed.
  • Fig. 2 are also opposite the microphones 14 arranged at regular intervals partitions 31 are marked on the transmission strip, between each of which a piezoelectric element 131 is arranged.
